if your limited to size there will be no guarantee if they only swap tanks.you need to find your source first and see what options you will have as far as refilling or swapping.if your space is limited then you cant swap and should buy an aluminum tank because aluminum last longer and doesn't rust as easily.i think the amount of times you can certify an aluminum tank is more than steel so if you stay in the hobby long enough you will save some money.I'm pretty sure if you swap tanks they will get mad if you try to specify which tank you want.
also if you buy a tank and do refills you usually have to leave it there for at least a day.it doesn't matter that much as your plants will survive.just something to consider if you live a distance away from the refill location.
K first of all, a welding supply shop will swap any tank you have with the exact same size!!
Telling him to buy an aluminium tank is pointless, since the shop you bring it to will give you what they have, not what you want.
I have never had to leave a tank anywhere for a day. I go in, give them the tank, an they simply give me another full one. Who cares if it is aluminium or steel?? The plants sure dont!!
A 5lb tank is a 5 lb tank no matter where ya get it exchanged at....A store isn't going to give you a 10 lb tank in exchange for a 5 lb tank That is a fact!!
It really isn't as hard as you are making this out to be!!
justintoxicated....You dont need a 10 lb tank! A 5 lb will fit yer cabinet just fine, an you wont have any modifications to do. Will last ya months, an refillin is as easy as gettin yer propane tank for the BB Que refilled. Not a big deal!!!!
